Determinants of Salary Dispersion in Organizations

Data from 821 colleges and universities were used to examine the determinants of the degree of wage dispersion in a set of more than 70 high-level university positions. Salary dispersion was positively related to the amount of dispersion in job tenure, private control, and type of institution (two-year college, four-year college, or university). Salary dispersion was negatively related to the proportion of administrative positions filled by insiders and to homogeneity in gender composition. The number of administrative positions (an index of the degree of specialization) increases dispersion when the positions were of a general administrative nature but decreased dispersion when position proliferation was related to the core activities of teaching and research.     

Union Effects on Earnings Dispersion in Australia, 1986–1994

In Australia a large decline in union density has occurred since the mid-1970s. This paper examines the effect of the decline in union density on the dispersion of earnings in Australia between 1986 and 1994. Changes in union density are found to have increased earnings dispersion for male employees over this period, but do not appear to have had a strong effect on earnings dispersion for female employees. The main cause of changes in earnings dispersion for both male and female employees has been an increase in the dispersion of earnings of non-union employees.     

Subnational institutional contingencies and executive pay dispersion

This paper investigates the impact of subnational institutional contingencies on executive pay dispersion structure and the relationship between pay dispersion and firm performance. Using executive compensation data on Chinese listed firms between 2000 and 2011, we find that executive pay dispersion is significantly lower in state-owned enterprises (SOEs), while is significantly higher in cross-listed firms and to a smaller degree in firms located in developed regions. There is also evidence that executive pay dispersion is smaller during the voluntary compensation disclosure period. After controlling for endogeneity of pay determination, we find that executive pay dispersion is positively associated with firm performance. In addition, the positive link between executive pay dispersion and firm performance is stronger in non-SOEs than in SOEs, and stronger in firms located in more developed regions than those not. Our findings are also robust to alternative measures of pay dispersion and firm performance.     

The impact of price adjustment costs on price dispersion in e-commerce

We analyze price dispersion using panel data from a large price comparison site. We use past pricing behavior to instrument for potential endogeneity of firms to select into certain product markets. Our main result is that greater price adjustment costs result in greater price dispersion even in e-commerce markets where price adjustment cost are thought to be negligible. Although the impact of price adjustment costs on price dispersion became weaker over time, the causal effect of price adjustment costs on price dispersion is still present at the end of our observation period. Our results are robust to many alternative empirical specifications. We also control for a range of alternative explanations of price dispersion, such as search cost, service differentiation, obfuscation, vertical restraints, and market structure.     

HOW DOES THE INTERNET INFLUENCE PRICE DISPERSION? EVIDENCE FROM THE AIRLINE INDUSTRY*

I estimate the Internet's effect on the level and dispersion of airline fares on a given route within and across firms. The results suggest that increases in Internet penetration reduce average price and lead to higher intrafirm price dispersion, while increases in Internet penetration do not affect interfirm price dispersion on a given route. Internet penetration affects average fares most in competitive markets. These results suggest that the Internet has significantly but subtlely influenced domestic airline competition. The effect of the Internet on prices and price dispersion is larger on direct flights.     

Number of sellers,average prices,and price dispersion

A variety of models provide differing predictions regarding the effect of an increase in the number of competitors in a market (seller density) on prices and price dispersion. We review different approaches to generating equilibrium price dispersion and then empirically estimate the relationship between seller density, average product price and price dispersion in the retail gasoline industry using four unique gasoline price data sets. Controlling for station-level characteristics, we find that an increase in station density consistently decreases both price levels and price dispersion across four geographical areas.     

Price Dispersion in Mortgage Markets

Using transaction‐level data on Canadian mortgage contracts, we document an increase in the average discount negotiated off the posted price and in rate dispersion. Our aim is to identify the beneficiaries of discounting and to test whether dispersion is caused by price discrimination. The standard explanation for dispersion in credit markets is risk‐based pricing. Our contracts are guaranteed by government‐backed insurance, so risk cannot be the main factor. We find that lenders set prices that reflect consumer bargaining leverage, not just costs. The presence of dispersion implies a lack of competition, but our results show this to be consumer specific.     

Collective Bargaining and Within-firm Wage Dispersion in Spain

This paper analyses the effect of collective bargaining on within‐firm wage dispersion for the case of Spain. What is relevant in the Spanish case is to compare the effect of the two basic levels of bargaining (firm and sector) on wage dispersion. By using the Oaxaca–Blinder decomposition, this paper concludes that collective agreements at firm level have a negative effect on wage dispersion. At the same time, firms that have signed these types of agreements show greater wage dispersion than those covered by agreements at the sector level, owing to the positive and compensating effect of firms’ and workers’ features.     

PRICE DISPERSION AND COMPETITION WITH DIFFERENTIATED SELLERS*

I measure price dispersion among differentiated retail gasoline sellers and study the relationship between dispersion and the local competitive environment. Significant price dispersion exists even after controlling for differences in station characteristics, and price differences between sellers change frequently. The extent of price dispersion is related to the density of local competition, but this relationship varies significantly depending on the type of seller and the composition of its competitors. These findings are consistent with interactions between seller and consumer heterogeneity that are not well understood in the existing price dispersion literature.

Is Airline Price Dispersion the Result of Careful Planning or Competitive Forces?

We develop a model of price dispersion to distinguish the impact of price discrimination from that of peak load pricing schemes or atypical competition resulting from the financial difficulties of the early 1990s. By utilizing three alternative measures of dispersion and appealing to economic theory for our specification, we find robust results suggesting an estrangement between price dispersion and price discrimination. While some discrimination continues to persist at monopolized endpoints, most dispersion is associated with fare wars and peak load pricing schemes.     

Missing Price Information and Its Impact on Equilibrium Price Dispersion: Evidence From Gasoline Signboards*

This article seeks to quantify the importance of price information in reducing consumer search costs and equilibrium price dispersion in a competitive setting. It exploits a natural experiment in the retail gasoline industry in which stations post the prices of only certain grades of gasoline on large street-side signboards, and not others, except where required by law. Differential-by-grade signboard information predicts a specific curvature in price dispersion across grades, and differentiates itself from other noninformational factors such as income and cost. The impact of readily-available price information on search and price dispersion is found to be exceptionally large.     

Rising Wage Inequality, Returns to Education and Labour Market Institutions: Evidence from Ireland

Institutional factors and increased supply of skilled labour have been advanced in an effort to explain why some countries have experienced smaller increases in earnings dispersion and in returns to education than the USA and the UK. Ireland has had a highly centralized wage bargaining structure and the supply of skilled labour has increased sharply in recent years; hence, relatively little change in earnings dispersion might be expected. We compare the distribution of earnings in Ireland in 1987 and 1994 and find a surprisingly large growth in earnings dispersion. In addition, using a decomposition technique, we find that much of this is accounted for by increasing returns to measured.     

Tyre price dispersion across retail outlets in the UK

We investigate price dispersion in a retail market (car tyres) characterised by outlets each selling a range of products, some of which are manufactured by their owners. Consumers face substantial price dispersion across outlets even for very tightly defined products. We show that this price dispersion has systematic components relating to retailer-manufacturer interactions. One specific result is that chains owned by manufacturers sell other manufacturers' tyres on average nearly 20% more expensively than do independent stores and over 11% more expensively than their own equivalent branded product.

Airline Market Power and Intertemporal Price Dispersion

This paper analyzes the empirical relationship between market structure and price dispersion in the airline markets connecting the U.K. and the Republic of Ireland. Price dispersion is measured by the Gini coefficient, calculated using fares posted on the Internet at specific days before takeoff. We control for passengers' heterogeneity in their purpose of travel, as well as for such peak periods as Christmas and Easter. Our finding of a negative correlation between competition and price dispersion suggests that competition is likely to hinder the airlines' ability to price discriminate, although this effect appears to be lessened in peak periods.     

Dissecting Between-Plant and Within-Plant Wage Dispersion: Evidence from Germany

Using rich linked employer–employee data for (West) Germany between 1996 and 2014, we conduct a decomposition analysis based on recentered influence function (RIF) regressions to analyze the relative contributions of various plant and worker characteristics to the rise in German wage dispersion. Moreover, we separately investigate the sources of between-plant and within-plant wage dispersion. We find that industry effects and the collective bargaining regime contribute the most to rising wage inequality. In the case of collective bargaining, both the decline in collective bargaining coverage and the increase in wage dispersion among the group of covered plants have played important roles.

Managing the Unexpected Across Space: Improvisation,Dispersion, and Performance in NPD Teams

Organizations are increasingly moving toward a team‐based structure for managing complex knowledge in new product development (NPD) projects. Such teams operate in an environment characterized by dynamic project requirements and emergent nonroutine issues, which can undermine their ability to achieve project objectives. Team improvisation—a collective, spontaneous, and creative action for identifying novel solutions to emergent problems—has been identified as a key team‐situated response to unexpected challenges to NPD team effectiveness. Geographic dispersion is increasingly becoming a reality for NPD teams that find themselves needing to improvise solutions to emergent challenges while attempting to leverage the knowledge of team members who are physically distributed across various locations. However, very little is known about how teams' improvisational actions affect performance when such actions are executed in increasingly dispersed teams. To address this gap in the literature, this paper draws on the emerging literature on different forms and degrees of team dispersion to understand how team improvisation affects team performance in such teams. In particular this paper takes into account both the structural and psychological facets of dispersion by considering the physical distance between team members, the configuration of the team across different sites, as well as the team members' perception of being distant from their teammates. Responses from 299 team leaders and team members of 71 NPD projects in the software industry were used to analyze the relationship between team improvisation and team performance, as well as the moderating effect of the three different conceptualizations of team dispersion. Results of the study indicate that team improvisation has a positive influence on project team performance by allowing team members to respond to unexpected challenges through creative and timely action. However, increasing degrees of team member dispersion (both structural and psychological) attenuate this relationship by making it difficult to have timely access to other team members' knowledge and by limiting real‐time interactions that may lead to the development of creative solutions. The results of this research offer guidance to managers about when to balance the desire to leverage expertise to cope with unexpected events. Moreover, the present paper provides directions for future research on improvisation and team dispersion. Future research is encouraged to investigate factors that may help highly dispersed teams to overcome the shortcomings of team dispersion in dealing with emergent events.     

The Effect of Interest Arbitration on Salary Dispersion Among Employers

This study uses Wisconsin teacher salary grid data for the period 1974–75 to 1984–85 to examine the impact of interest arbitration on wage determination and salary dispersion among employers. Models of wage determination are developed and estimated using observations from a period before and after implementation of arbitration. These wage equations are then used to decompose the difference in the variance of the log wages for the two periods. The results suggest that although observed salary dispersion is greater at the statewide level under arbitration, the imposition of arbitration mitigates the impact of measured factors on wage determination, resulting in less salary dispersion within small clusters of school districts, all else constant.
